JOHN A. COREY, OF HOPE VALLEY, RHODE ISLAND.

CARRIAGE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 481,749, dated August30, 1892.

Application filed June 15, 1892.

To all whom it may concern.-

Be it known that I, JOHN A. COREY, of Hope Valley, in the county ofWashington and State of Rhode Island, have invented certain new anduseful Improvements in Carriage- Wrenches; and I do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

This invention relates to that class of Wrenches known ascarriage-wrenches,. and is used for turning the screw-nuts on the axlesof vehicles. It is fully illustrated in the accompanying drawings.

Figure 1 is a front elevation of the Wrench. Fig. 2 shows a sideelevation. Fig. 3 represents the way in which the wrench and nut areheld on the hub-band of the wheel While the axle is being greased.

This wrench consists of a fiat shank I), having a square head a made onone end with an opening through it of the proper size to go easily overthe square portion of the nut 11. The other end of the shank bterminates in a handle d. The whole wrench is preferably made in onestraight piece of steel by dropforging and afterward bending the handled up to a right angle tothe shank, as shown in the drawings. The head ais made as light as is consistent with sufficient strength to turn thenut. Two cheek-flanges e e are made. one on each side of the opening inthe head for the purpose of strengthening the head and preventing theWrench from twisting around sidewise when force is applied to the handle(1 to turn a nut off of an axle. A small fiat spring 0 is riveted to theouter bar of the head a and bent up nearly at a right angle to the barto which it is fastened, the object of which is to hold the nut fromdropping when it comes serial No. 436,775. (No model.)

held by a rivet passing through the strip and the shank to form aspring-clasp m, the object of which is to afford means for attaching thewrench to the wheel when the latter is taken off of the axle and hold itwith the nutn while the operator is attending to the axle. Fig. 3 showshow this is done. The two spring ends of the clasp are pushed one on theinside and the other on the outside of the thin edge of the hub-band t,which is held between them with sufficient pressure to retain the wrenchin position, as shown in Fig. 3, a section of the two parts of thespring-clam p being shown on the right side of the hub with the hub-bandbetween them. By these means the necessity of handling and laying thenut down where it will be liable to have sand or dirt stick to itbecause of its greasy condition is avoided, also the chance of soilingthe fingers in putting it on the axle, for when the wheel is replaced onthe axle the wrench and nut will be in the most convenient position foruse.

Having thus described my improved wrench, I claim as my invention anddesire to secure by Letters Patent- A carriage-wrench consisting of ashank having a light square open head to receive the nut withcheek-flanges on either side of the opening and a spring attached to itsouter bar to hold the nut when off the axle,in combination with aspring-clasp attached to the shank, substantially as described, for thepurpose of holding the wrench, as herein set forth.

JOHN A. COREY.
